Abstract: The title triazole compound, C₁₅H₈Cl₄N₄S·C₃H₇NO, has been obtained as an unexpected product when attempting to prepare Schiff bases of thiocarbohydrazide (TCH). The triazole ring is planar within 0.004  (8)  Å because of conjugation. The dihedral angles between the 1,2,4-triazole ring and the two benzene rings are 24.9  (2) and 70.0  (2)°. The interplanar angle between the two benzene rings is 83.4  (2)°. The packing of the molecules is stabilized both by van der Waals interactions and by N-HO intermolecular hydrogen bonds between the triazole N atom and the carbonyl O atom of the dimethylformamide solvent molecule.
